Scatter plots showing correlations of several spectral properties over time. Coloured pixels are pixels within the flaring region, where color refers to time. The background are pixels from the full field of view. a) The correlation between the h and k line intensities with lines R_kh = 1, and R_kh = 2 shown. b) The scatter plot of R_kh with k-line intensity. c) The scatter plot of the k-line intensity and k-line centroid velocity. d) The correlation between the k-line and h-line centroid velocities
